Python program to Multiply two integers|in 5ways
In this tutorial, we will discuss the Python program to Multiply two integers|in 5ways
In this post, we are going to learn how to find multiplication of two numbers via different 5 ways in Python language
Program to Multiply two integers
Program to Multiply two integers – standard method
Program 1
#Python program to mutipy two numbers
num1=15
num2=16
mul=num1 * num2;
print("Multiplication of two numbers: ",mul)
When the above code is executed, it produces the following result
Multiplication of two numbers: 240
- Integer variable num1 and num2 both are declared and initialized
- the num1 and num2 both are multiplied together and the value is assigned to the integer variable mul
- finally the program is displayed the output using print() function
Program to Multiply two integers – using user input
Program 2
#Python program to mutipy two numbers
num1=int(input("Enter first number: "))
num2=int(input("Enter second number: "))
#input numbers from the user
mul=num1 * num2;#caculate multipication
print("Multipication of two numbers: ",mul)
#display output
When the above code is executed, it produces the following result
Enter first number: 12 Enter second number: 24 Multiplication of two numbers: 288
Approach
- Integer variable num1 and num2 both are declared,
- The program takes input from the user
- Then the user enters the input value for num1, num2
- the program will read the input and store the variables in num1, num2.
- the num1 and num2 both are multiplied together and the value is assigned to the integer variable mul
- finally the program is displayed the output using print() function
Program to Multiply two integers – using function
Program 3
#Python program to multiply two numbers using function
def multiply(num1,num2):#function definition
product=num1 * num2
return product
num1=int(input("Enter first number "))
num2=int(input("Enter second number "))
#input numbers from the user
result=multiply(num1,num2)#caling the function
print("Multipication of two numbers: ",result)
#display output
When the above code is executed, it produces the following result
Enter first number 12 Enter second number 21 Multiplication of two numbers: 252
Approach
- Integer variable num1 and num2 both are declared,
- The program takes input from the user
- Then the user enters the input value for num1, num2
- the program will read the input store the variables in num1, num2.
- define the function for find product of two numbers
- When we call the function, the num1 and num2 both are multiplied together
- Then the value is assigned to the integer variable result
- finally the program is displayed the output using print() function
Program to Multiply two integers – using recursion
Program 4
def product(x,y):
if(x<y):
return product(y,x)
elif(y!=0):
return (x+product(x,y-1))
else:
return 0
x=int(input("Enter first number: "))
y=int(input("Enter second number: "))
print("Product is ", product(x,y))
When the above code is executed, it produces the following result
Enter first number: 100
Enter second number: 50
('Product is ', 5000)
Approach
- Integer variable x and y both are declared,
- The program takes input from the user
- Then the user enters the input value for x and y
- the program will read the input store the variables in x , y.
- define the recursive function for multiply two numbers
- When we call the function, the x and y both are multiplied recursively
- finally the program is displayed the output using print() function
Program to Multiply two integers – using without * operator
Program 5
num1=int(input("Enter first number: "))
num2=int(input("Enter second number: "))
product=0
for i in range(1,num2+1):
product=product+num1
print("Product is ", product)
When the above code is executed, it produces the following result
Enter first number: 50 Enter second number: 60 Product is 3000
